Application mamar-ch e, 1922. vserial No. 541,292.

To all whom/.it may concern:

Be it known that we, WILLIAM BPAINTER and ELIZABETH A.' REEVES, citizensof the United States of America,'residing at River Rouge, in the countyof `Wayne and State of Michigan, have invented certain new. and usefulimprovements in Attachments for Ovens, lof which the following is 'aspecification, reference being had therein to the ac; companyingdrawings. d

This invention relates to ovens and particularly to trays which aremovable within the same.

In the present state of thev art varius devices have been found whichare provided with a plurality of removable vertically spaced trays orshelves. However', whenever it is desired to move 'tray vertically withrespect toa burnerbeneath the bottom of the oven it sometimes becomesnecessary to open the oven door and to keep the same open during theentire operation of changingor adjusting the trays. This method lowersmaterially the temperature withinA the oven. Moreover', after the ovenhas been heated for a considerable length of time the trays becomev hotand it is necessary to use gripping meansfytoremove and replace thetrays. v y .y

Itis the object of the present invention to overcome all of theobjectionable features referred to above and to provide a simplemechanical construction' which may be advantageously used in any type ofoven.

To this end the invention consists in the construction as hereinafterset forth.

In the drawing v Fig. l is a top plan view of an oven with parts brokenaway.

Fig. 2 is a longitudinal sectional view taken on the line 21-2 of Figure1.

Fig. 3 is a transverse sectional View taken on line 3-3 of Figure 2.

Fig. 4 is an end view with partsbroken away.

construction.

Referring now to the drawing in which like characters of referencedesignate corresponding parts throughout the several views, the numeral1 designates an oven casing provided with the usual lining 2 andintermediate packing 3. u

A plurality of spaced vertical guide memv bers 4 are secured tooppositeend walls of the lining 2 and are adapted to engage lF ig. 5 1san end elevation of a modified j spaced slots 5 formed in theends ofamovable tray 6. A pair of iexible 'members 7 are terminally secured tothe' tray adjacent to the slots 5 and are secured intermediate theirends to the lower ends of a .pair of flexiblemembers 8 and 9respectively, which are trained over a pair of aligned pulleys 10secured to the upper wallof the lining adjacent to the oppositeendsthereof. The iiexible member 9 vis also trained over a pulley 11which is secured to the up'perwall of the lining intermediate' thealigned pulleys l0l and is offset with respect thereto. A flexiblemember 12 is secured to the free ends of the flexible members 8 and 9and formed respectively in the oven casing-and lining. A hollow handlemember 14 is secured to the free end of the flexible member.`

vextends through aligned openings `1,3 and 13k i Various means may beemployed for re-` taining the `trays in adjusted position andin thepreferred embodimentof the `inventiony a relativelyl'narrow notch 1.5isfo'rmed inthe oven casing` in communication with "the opening 13andpis adapted 'to' receive and frrictionally hold a portion Aof theflexible member 12. y j

In the modified form ofthe'invention,l a plurality of vertically spacedpegs or `studs 1G are secured by 'any suitable means to "the oven casingbeneath the lopening '13. L `These pegs are adapted to extend throughvthe handle member 14 to retain the trays in'any desired position ofadjustment.

With the construction described the trays may be easily and quicklymoved to any position of vertical adjustment withinV the oven withoutopening the oven door. d j

While it is believed thatv from the foregoing description the nature andadvantages of the invention willl be readily apparent, we desire to have1t understood that we do notl limit ourselves to what is herein shownand described, and that such changes may be resorted to when desired asfall within the cured to said tray, pulleys secured to one wall of saidoven, flexible members secured to the flexible members aforesaid andtrained over said pulleys, a pulley secured to one Wall of said oven andsupporting one of the last mentioned flexible members, and a flexiblemember secured to both of the last mentioned flexible members andextending through said oven. v

2. rlhe combination with an oven, of guide members secured to said oven,a movable tray located in said oven having slots formed therein engagingsaid guide members, flexible members terminally secured to said tray, aVpair of pulleyssecured to said oven, flexible members secured to theflexible members aforesaid and trained over said pulleys, a pulleysecured to said oven and supporting oneof the last mentioned flexiblemembers, and a exible member secured to both of' the last mentionedflexible members and extending through said oven, said oven having notchformed thereinA adapted to receive and frictionally hold a portion ofthe last mentioned flexible member.

3,. The combination with an oven, of a movable tray located in saidoven, flexible i' memberssecured to said tray, a pair of pulleys securedto said oven, flexible members secured'to the flexible members aforesaidand trained over said pulleys, a pulley secured to said oven andsupporting one of the last mentioned flexible members, said oven havingan opening formed therein, and a flexible member secured to both of thelast mentonedflexible fmembers and extending through the opening in saidoven, said oven also having anotch formedtherein in communication Withsaid opening adapted to receive and frictionally hold a portion of thelast mentioned flexible member.

, 4. The combination with an oven, of a movable tray located therein,guide means for saidl tray, flexible members terminally secured to-said'tray atthe opposite ends thereof, a pair of aligned pulleyssecured vto the upper vvall of said oven, flexible members secured tothe flexible members aforesaid intermediate the ends thereof and trainedover said pulleys, a pulley secured to i the upper Wall of said 'ovenintermediate the aligned pulleys and offset With respect thereto, thelast mentioned pulley supporting one of the last mentioned flexiblemembers, and

a flexible member secured 'to the free ends of both of the lastmentioned flexible members and extending throughsaid oven, said ovenhaving a notch formed thereinadapted to receive and frictionally hold aportion of GfThe combination With'an oven, of a y movable tray locatedin said oven, flexible members secured lto said tray, pulleys secured toone Wall of said'oven, flexible members secured to the flexible ymembersaforesaid and trained over said pulleysa` pulley y secured to one Wallof said oven and supporting one of the` last vnl'ientioned flexiblemembers, a flexible'member secured to both of the last mentionedflexible members, and means engageable with the last mentioned flexiblemember for retaining said tray in any position of adjustment.

In testimony whereof We aflixour si'gnatures.
